Guidance and manufacturer's declaration – electromagnetic immunity
The Fingertip Oximeter is intended for use in the electromagnetic environment
specified below. The customer or the user of the Fingertip Oximeter should
assure that it is used in such an electromagnetic environment.
IMMUNITY
TEST
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV bro-
adcast cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the Fingertip Oximeter is used exceeds
themapplicable RF compliance level above, the Fingertip Oximeter should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

GUIDANCE
Portable and mobile RF communications
equipment should be used no closer to
any part of the Fingertip Oximeter, in-
cluding cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d= 1.2 √P
d= 1.2 √P 80MHz to 800MHz
d= 2.3 √P 800MHz to 2.5GHz
Where P is the maximum output power ra-
ting of the transmitter in watts (W) accor-
ding to the transmitter manufacturer and d
is the recommended separation distance
in metres (m).
b
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the com-
a
pliance level in each frequency range.
Interference may occur in the vicinity of
equipment marked with
the following symbol:
